Routing within the VM Network

Is there any possible way to change your routing, or ask too get it changed?

Over the last 2 months i've been routed different from my location (Swansea).
Which has lead to me gaining between 5-8 addtional ms, which quite frankly i do not wan't.
Before my routing path to some servers would be:

Swansea > Guildford > Wind(windsor?) > Poplar > Telehouse. Which lead to me having ~12ms to gaming servers.

Now my connection ONLY uses the following:

Swansea > Birmingham > Manchester > Northampton > poplar > Telehouse..

Why on earth does it go half way around the country?

Example

1 9 ms 7 ms 7 ms myip.cable.virginmedia.com [82.
20.159.1]
2 11 ms 11 ms 11 ms swan-core-1a-ge-300-2482.network.virginmedia.net
[80.0.254.117]
3 12 ms 11 ms 11 ms brhm-bb-1a-ge-130-0.network.virginmedia.net [212
.43.162.105]
4 17 ms 16 ms 13 ms manc-bb-1b-ae5-0.network.virginmedia.net [213.10
5.174.186]
5 22 ms 18 ms 21 ms popl-bb-1a-as4-0.network.virginmedia.net [212.43
.162.85]
6 20 ms 33 ms 19 ms popl-bb-1b-ae0-0.network.virginmedia.net [213.10
5.174.230]
7 22 ms 18 ms 19 ms tele-ic-5-ae0-0.network.virginmedia.net [213.105
.159.117]
8 23 ms 23 ms 21 ms 62.253.174.70
9 25 ms 28 ms 24 ms racksrv-162.gw.goscomb.net [46.17.60.162]
10 23 ms 23 ms 25 ms 193.33.187.133

Before my routing before was Guilford > windsor > Poplar, Which resulted in 12-14ms final stop.

From the 1st of March (this is when the routing changed)



This is current



Maybe im being picky, maybe it's my ocd, but making my connection worse is quite annoying.

Re: Routing within the VM Network

I only see one graph (though when I did see two there was very little difference)

You can't get your routing changed. At least not easily, or individually. You could try forcing a change of IP, which might change routing. I've seen increases of 14ms on VM from the above.

Distance and latency have a funny weird interaction on VM's network. Birmingham to London takes longer than Manchester to London. A lot of VM traffic to Amsterdam also takes twice as long as it should, because it takes a shorter (!) path.

I don't think it's being picky - I get similarly peeved when BT do a MPLS reroute or turn interleaving on on my line (12-16ms extra latency) as I notice an immediate difference in gaming and remote desktop and VPN performance.

VM has made a serious turn towards cheap, fat, high latency pipes lately, at all levels of their network.

Re: Routing within the VM Network



Easier to see the jump's, that is the jump that has stayed on the connection (being routed different)

With additonal latency (Jitter) it makes the pingtimes to the gaming servers awful. majority of uk servers now, im stuck to 20-25ms. Where as when i was on my previous 1mb adsl line I had 16-17ms.

Cloning the MAC is the easiest way, not a function the SH lets you perform though.

Change the MAC. Cloning will just give you the same IP again.

Re: Routing within the VM Network

Do what craig said in post #6. You can't change the MAC of your Superhub by any standard means and if by some miracle you did it by foul means it wouldn't work on the VM network. If you are in modem mode the router MAC is what the IP gets based on - change the router (or its MAC) and you get a new IP. Do it too many times over a short timescale and you get rewarded with a connection that doesn't get issued an IP unless you go back to one of the earlier MACs that were used.

Re: Routing within the VM Network

Doesn't look like he's using a router at all. Tracert suggests straight to modem.

Re: Routing within the VM Network

I was using the superhub in routermode, now switched to modem mode + D-link dir.

However nothing has changed

Re: Routing within the VM Network

Weird, your router should be showing as hop 1 in both cases but it's not.
